Why Save The Trees?
Grades 6-9 SOL OBJECTIVES: LA 6.1,6.2,6.3d,6.5,6.6 MA 6.18,6.20,6.7,6.8,6.9
SCI 6.9, 6.1 a-k, 6.2d SS USII.5 a-d, USII.7, USII.8
Purpose
To understand that trees are a valuable natural resource, and without their survival, technology and life as we know it can change drastically.
Context
Until the fifth grade, most students understand that trees are a natural resource and that they supply us with everything from paper to the homes which we live. Transferring the concept on a higher level thinking realm is one of the most difficult challenges we face teaching, and the most difficult concept children face learning. If you were to do a K-W-L with students in the younger years, all trees are the same, and there is no concept of how it is pureed into mash for paper, cut into lumber to build yet alone used for energy.
By the time they get to 5th grade student interest increases and it becomes harder to find a method to
keep their interest. For kids, finding out that there are over 20,000 types of trees, pulls in their attention. For the teacher it gives plenty of room to expand and direct the curriculum and instruction to higher level thinking skills and knowledge.
This lesson introduces the history of trees, not just the type of trees. It discusses why they must be saved in order to keep benefit humans, animals and our Earth. Students will learn by about the history of plants and that they have been around on the earth longer then any other organism. This lesson will focus on the past use of our natural resource and the options we have in saving trees to continue providing some of the groundwork for the things we need to survive in the next century.
Students will be introduced to the "Tree Doctor" and learn what they can do to help save the trees. The will also be made aware of occupations that are focused in the area of forestry.

Websites can be downloaded to a CD in case the internet is down, you can work off line
Worksheets-graphic organizers
VCR/DVD players, video and computer projectors
Software- Inspiration, National Geographic, WINDOWS on Science
Motivation
In the morning have small saplings around the room and the lab set for experiment.
Show United Streaming Video -The Biggest and Oldest Living Things. Found on unitedstreaming.com
o An Introduction to Trees
o Learning About The Past
o Appreciating Trees
Have students preview their QUESTO sheet. This sheet will direct them to websites and activities that will help them transfer what they know, what they need to learn and how they can compile data to determine what they can do.
By using the computer lab and a main computer, show the students a tabbed version of the websites they will visit today. Leave a tile version on the screen so that navigating will be easier.
This web quest is intended to lead students to understand that our natural resources are more and more limited. That the tree has been around longer than any other organism and in our life time we may see it become extinct. Students will also be motivated to support the things we need to do to save the trees for a better future.
Development
Discussion:Where do trees get the nutrients they need to grow?
What do trees release into the atmosphere that humans need?
What do we know about tree growth and age?
Objectives
o Students will understand how humans, animals, and the earth benefit from trees
o Students will learn about the history of the oldest living thing, and their future
o Students will work through team activities and web quest online and learn how to look for specific information.
Ask students to tell you how we benefit from trees.
Have the students look through the QUESTO and ask individual teams to connect the information from what they think the articles will be about with something they have learned before.
As a class, between web pages, brainstorm things that will help keep healthier plants.
Have poster paper up to create a mapping of ideas.
Have a poster board for words and definitions students may request information about.
The following web pages are used in the web quest:
Found at dsc.discovery.com- The age and size of trees around the world
This article will reveal the of age and size of trees around the world.
Found at dsc.discovery.com/news - Types of organisms can kill trees
This article will give students a sense of what types of organisms can kill trees.
On the freenetwork.umn.edu/kids/ site you will find activities and information.
United Streaming Video online -Trees: The Biggest and Oldest Living Things
Found at domtar.com/ARBRE/english/
The Tree World. This site will provide a ton of activities. Students can use the dictionary to identify vocabulary words. Play games and take quizzes, this site also includes experiments. Crossword puzzle-uses for trees. How to protect trees.
Wesavetrees.com website has a great article called:What Can We Do to Save Trees?
Found at epa.gov/epaoswer/osw/kids/pdfs/k-3.pdf
Excellent site for extended activities
Lab Project: Create a terrarium to grow and take home.
Assessment
Students will present their data in their notebooks.
Students will be able to discuss the objective of the lesson and finish the K-W-L sheet
Students will make a terrarium and experiment with different soils/ document data.
Students will complete a final project of their choice for a graded assignment using at least three software applications WORD, PUBLISHER, DIGITAL, VIDEO EQUIPMENT, POWER POINT, INSPIRATION SOFTWARE, NATIONAL GEOGRAPHIC MAGAZINES OR WINDOWS ON SCIENCE
At the end of the week a Q&A sheet on Save the Water will be passed out and will ask similar questions
Where does it come from?
How much did we have?
What do we have now, why less?
What is water used for?
What will happen without it?
What can we do to save it?
Students may use any resources to complete the sheet.
There is a saying: "Ancestors plant trees so that their offspring can have shade."
Extensions
Language: The Lorax by Dr. Seuss
Math: Measure the age of a tree by it's rings
Science: Visit a paper mill or newspaper plant
Social Science: Join and environmental club
